The students in one gym class receive a self-esteem program as part of their sports training. To evaluate the program, a researcher measures self-esteem for the students before and after the program and compares their scores with those from another class that did not receive the program but was measured at the same two times. What kind of design is being used?
a. between-subjects design
b. within-subjects design
c. repeated measures design
d. mixed design
What is compensatory rivalry? Illustrate with an example.
What will be an ideal response?
In a changing-criterion design
a. changes in behavior are measured at different points in time.
b. changes in behavior cannot be attributed to the reinforcement contingency.
c. the criterion for reinforcement remains constant over the course of the experiment.
d. the criterion for reinforcement is changed over the course of the experiment.
A two-factor study with two levels of factor A and three levels of factor B uses a separate group of n = 5 participants in each treatment condition. How many participants are needed for the entire study?
a. 5
b. 10
c. 25
d. 30
What is the regression threat in a single group design?
What will be an ideal response?
In a multiple-baseline design
a. the length of the baseline period is the same for all of the subjects in the experiment.
b. the behavior of the subjects is expected to revert to baseline levels after the removal of the independent variable.
c. the length of the baseline period is different for different subjects or different behaviors prior to the introduction of the independent variable.
d. the occurrence of carryover effects cannot be assessed.
Which outcome is possible in a 2 x 2 factorial design?
a. four main effects and no interaction
b. four main effects and no interaction
c. no main effect for either factor but an interaction
d. four interactions
What is the history threat in a single group design?
What will be an ideal response?
An alternating-treatments is designed is used
a. when several samples of the subjects' behavior in different conditions of the experiment are desired in a small-n design that precludes counterbalancing.
b. when there is no danger of a carryover effect.
c. when the experimenter has matched the experimental and control groups.
d. when there is no baseline measure of the dependent variable.
Which outcome is possible in a 2 x 2 factorial design?
a. two main effects and two interactions
b. a main effect for one factor, no main effect for the other factor, and two interactions
c. no main effect for either factor and one interaction
d. a four-way interaction
